Compact System in Level Control ELK 4/ ELK 4F Main Features : Ayvaz Compact System GALAXY ELK 4 / ELK 4F work according conductivity mesurement principle. ELK 4/ELK 4F capable of display- ing 4 levels in conductor liquids ; 4 levels, each with one contact point : - High level alarm - Low level alarm - Pump start, - Pump stop. ELK 4/ELK 4F ensure the control of all functions inside the panel. No external control device is required. Function : Conductivity of liquid is utilized for displaying the level of liquid. some liquids are conductor, that is, such liquids allow electric current to go through themselves. Minimum conductivity of liquid must be measured in order to ensure safe functioning of device. Two situa- tions can be detected tank to such characteristic of liquids : - Electrode rod dipped/exposed, - Switch point accessed / not accessed. Before the assembly, sizes of electrode rods must be addapted according to contact levels. (For example; maximum/minimum alarm, vale of pump control.)
